While all systems with Thunderbolt 3 Controllers have a USB Type-C port, having a USB Type-C port does not ensure that you have a Thunderbolt 3 Controller.
Refer to this Dell knowledge-base article to ensure your system has the Thunderbolt 3 Controller required to use the Dell Thunderbolt Dock (TB16): Systems with USB Type-C ports that lack a Thunderbolt 3 controller.

NOTE: A system requiring more than a 130 Watt AC Adapter must have its own AC power adapter attached to the system in addition to the dock AC Adapter.

NOTE: Ensure the latest BIOS revision available is installed before connecting to these docks.

NOTE: To use a third external monitor, the notebook's display must be disabled.

Not supported.

NOTE: Resolution support is also dependent on the monitor's Extended Display Identification Data (EDID) resolution. For example, a 27" monitor with a native resolution of 2560 x 1440 can be set to 1920 x 1080 with a 23" monitor also set to 1920 x 1080, as well. This would appear to meet the criteria for 2 displays on the WD15. However, the WD15 dock will see the 27" monitor at its native resolution and video to a second monitor may be distorted.
